Почему я люблю языки с сильной системой типов, проверяемой статическим анализом кода — хорошо написанная программа является своей собственной спецификацией и позволяет выражать через язык программирования законы существования предметной области. Когда-то давно я писал на ActionScript. Там была система типов, но вот десериализация JSON'ов по-умолчанию была в какой-то общий Object, к полям которого нужно было обращаться ["по_строковому_имени"]. В один момент мне потребовалось написать что-то на C#, который я совсем не знал, я стал гуглить, как десериализовать JSON, и с удивлением обнаружил кучу советов заранее объявить класс со всеми нужными полями и десериализовать в него. "Какой ужас!", — подумал я тогда, — "Это же дико неудобно! А если я не знаю полей JSON? А если их много? Отвратительный язык!" Теперь то я прекрасно понимаю, что JSON это контракт, и что правильная десериализация только такая и должна быть, и что в хорошем API в одном поле никогда не бывает данных принципиально разных типов, и так далее. Нет, если вы набиваете вечерами пет-проект или сидите бессонную ночь на хакатоне, нет ничего плохого в том, чтобы взять простой язык с динамическими типами вроде JavaScript или Python, не требующий описывать данные. Но вот в энтерпрайзе, особенно когда над одним проектом работает много людей (а бывает это очень часто) — хорошее использование системы типов убережёт разработчиков от огромного количества ошибок, будет бить их по рукам, когда они пытаются сделать что-то не то, и будет подсказывать, когда они не уверены в чём-то. С помощью статической типизации можно на уровне кода обозначить правила, по которым ведёт себя предметная область вашей программы в реальном мире. Разработчику не только будет сложно их нарушить, но он ещё и станет узнавать какие-то вещи, которые мог не знать раньше. Например, если мы делаем медицинскую CRM, и больница заводит новых пациентов только тогда, когда знает их группу крови, мы можем объявить тип "Пациент" (или, если точнее, "Карта пациента") и запретить создавать экземпляры этого типа, не передав в конструктор группу крови (которая, в свою очередь, тоже является типом, вероятнее всего ValueObject'ом). Если новый программист пришёл в проект, он, во-первых, не сможет записать в БД некорректную карту пациента. Понятно, мы не учитываем случаи, когда новый программист переделывает модели предметной области — это будет хорошо видно на кодревью. А, во-вторых, даже если ему никто не сказал, что пациенты должны быть с группой крови, он узнает это из кода. И уже будет понимать, что в тех процессах реальной жизни, которые он описывает кодом, карта пациента создаётся только при наличии группы крови. А, значит, нужно искать какой-то способ сначала эту группу крови получить, и только потом создавать карту. Программирование моделирует реальный процесс. В настоящей работе даже на языках с типами, конечно, без должного контроля можно написать что угодно. Нужна управленческая воля, компетентность руководства, понимание опасности техдолга, в идеале отдельные должности для архитекторов, опытные лиды и старшие разработчики. Но когда всё это есть, можно отсекать много проблем ещё на старте и проще погружать новичков. #dev

Storm x FIVA — New Strategies for Earning on Liquidity Storm Trade has partnered with FIVA, the first yield tokenization protocol on $TON. 💪 What's the benefits for liquidity providers? Your SLP (Storm Liquidity Provider) tokens can now do more than just sit in the pool earning trading fees. With FIVA, they become flexible financial instruments that let you boost profits, access future rewards early, and diversify income streams: 🟠Fixed Yield via PT (Principal Tokens). Lock in predictable returns by tokenizing your SLP’s expected income. A great tool for hedging against volatility — your yield is secured at the time of tokenization. 🟠Accelerated RP Farming with YT (Yield Tokens). YT lets you earn Storm RP at a significantly faster rate than traditional LP farming. If you expect yield to rise, YTs offer additional upside — without liquidation risks. 🟠Immediate Access to Future Yield. Need liquidity now? Sell your YT tokens on FIVA’s integrated DEX and unlock future earnings today, while holding onto PT tokens that convert back into SLPs at maturity. 🟠Extra Income from Yield Token Trading. PT/ YT tokens are tradable on FIVA’s native DEX — allowing you to earn from trading fees while avoiding impermanent loss (no need to pair tokens in pools). 🟠Multi-Layered Yield from a Single Position. Earn from several sources: • Base APR from Storm • RP farming • FIVA bonus rewards • DEX trading commissions 📈LP yield of 🫶Storm Trade is already strong — 10–25% annually from trading volume, liquidations, and protocol incentives. With FIVA, liquidity providers can manage yield flows more strategically, optimize returns, and hedge against market conditions. 🤝 Even if you're just getting started with liquidity provision, you can begin with the basics and gradually move on to more advanced strategies. Dive deeper into the mechanics here. #Web3#DeFi#StormTrade#Fiva

TON Space x EVAA integration ❤️ Recently the non-custodial version of the @wallet — TON Space integrated EVAA Protocol. This is the great opportunity for EVAA, considering that in Q2 Telegram the wallet plans to hit the US market. However, after the end of the TON Foundation boosts for #EVAA, the overall APR % on supply dropped significantly, so now it is more profitable to farm 😇 EVAA XP additionally using other #DeFi projects – #StormTrade and #FIVA. 🪙 The interface itself has undergone a small update. A new section has appeared — "Earn". You can clearly see how the percentage changes after each Supply/Borrow loop through #Tonstakers (looping strategy). If you use $tsTON, then EVAA XP doubles after each loop. 📈 Interest rates on $USDT loans in the LP pool have been reduced. Now it will be less expensive to use the "looping" strategy through SLP. LP pool works very well with Storm. Btw 🪙Storm Trade recently partners with 👍FIVA too. ➡️Add SLP to EVAA. ➡️Borrow $TON or $USDT. ➡️Put it in Storm Trade again. ➡️Repeat. Remember the risks. 🎙 Recently, the co-founders of #VAA held two broadcasts. In one of them, CTO Vlad (@sepezho) touched on the topic of oracles and the risks of liquidations (on Ru lang). In the second podcast, CEO Vlad participated, discussing the DeFi segment on TON in general (on Ru lang too). Therefore, if you have nothing to do in your free time, you can check it out.
